Description:

CROSS-REFERENCE TO RELATED APPLICATION

[0001] This application claims benefit under 35 U.S.C. §119(e) of
U.S. Provisional Application having Ser. No. 61612386 filed on Mar. 18,
2012, which is hereby incorporated by reference herein in its entirety.

FIELD OF INVENTION

[0002] This invention relates to a hand-worn device such as a watch, and
in particular a hand-worn device with programmable memory.

BACKGROUND OF INVENTION

[0003] Traditional hand-worn devices such as watches allow a user to know
the present time. Nowadays, more and more functions are incorporated into
the watch, however it is difficult to find a watch that all functions are
desired by the user. Also, more functions generally means a larger
volume, higher cost and more power consumption.

SUMMARY OF INVENTION

[0004] In the light of the foregoing background, it is an object of the
present invention to provide an alternate hand-worn device that solves at
least one of the aforementioned problems.

[0005] Accordingly, the present invention, in one aspect, is an apparatus
comprising a display unit, an attachment strap attached to the display
unit where the attachment strap is adapted to attach the apparatus to a
user, and a processing unit electrically coupled to the display unit. The
apparatus further comprises a programmable memory, the programmable
memory having at least one operation algorithm installable therein. The
processing unit runs one of the operation algorithms to operate the
apparatus at a corresponding operation mode, where at least one parameter
is displayed on the display unit.

[0006] In an exemplary embodiment of the present invention, the apparatus
further comprises a communication unit electrically coupled to the
processing unit. The communication unit is adapted to receive the
operation algorithm from a remote device and install in the programmable
memory.

[0007] In a further embodiment, the communication unit is adapted to
transmit the displayed parameter to the remote device. In another
embodiment, the communication unit is adapted to communicate with at
least one sensor in a sensing device for obtaining the parameter for
display.

[0008] In yet another embodiment, the sensing device comprises a chest
belt and the sensor comprises a heart rate sensor

[0009] In an exemplary embodiment of the present invention, the operation
algorithm is removable from the programmable memory.

[0010] In another embodiment, the apparatus further comprises at least one
sensor for detecting the parameters for display. The sensor comprises an
accelerometer.

[0011] There are many advantages to the present invention. A first
advantage is that the programmable memory allows the user to install only
the desired operation algorithms, while avoiding installing any undesired
operation algorithms. As a result, the limited resource of memory space
is most efficiently utilized for optimized performance of the device. By
communicating to an external sensor, the range of parameters detected and
displayed can be expanded.

[0012] A second advantage is that the user can download from a host device
and install a new operation algorithm onto the apparatus, so that the
apparatus can be re-configured to perform a new function when such new
operation algorithm is invoked. In one embodiment, the apparatus can
perform not only as a real-time clock but also as a weather forecasting
station, an exercise monitoring device, a calorie coach and also a
heart-rate monitor.

[0013] Another advantage of the present invention is that the choice and
settings of the display unit is optimized for minimum power consumption,
allowing the majority of the power to be used in communication and/or
detection of parameters.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] As used herein and in the claims, "comprising" means including the
following elements but not excluding others.

[0022] As used herein and in the claims, "couple" or "connect" refers to
electrical coupling or connection either directly or indirectly via one
or more electrical means unless otherwise stated.

[0023] Referring now to FIG. 1, the first embodiment of the present
invention is a hand-worn apparatus or device 20 such as a watch, having a
display unit 22 and an attachment strap 24 for attaching the device 20 to
the wrist of a user. A plurality of control buttons 26 are provided
adjacent to the display unit 22 for controlling the operation of the
device 20. In one embodiment, there are three control buttons on one side
of the apparatus 20 for the users to select and control the apparatus 20.

[0024] Referring now to FIG. 2, the display unit 22 is electrically
coupled to a processing unit 28. The processing unit 28 is in turn
coupled to a programmable memory 30 and a communication unit 32. The
communication unit 32 is adapted to communicate with a remote device 34,
a sensing device 36, or both. In an exemplary embodiment, the
communication unit 32 is a wireless transceiver. In a further embodiment,
the ANT+ (or ANT PLUS) protocol is used for data exchange between the
hand worn apparatus 20 and the sensing device 36. In yet another
embodiment, the apparatus 20 is adapted to communicate with devices
running an Android application for software download or data upload. In
other embodiments, the communication unit 32 is adapted to communicate
through wired mechanisms. The programmable memory 30 can be installed
with at least one operation algorithms. Each operation algorithm is
runnable on its own by the processing unit 28, and each operation
algorithm corresponds to a separate operation mode of the device 20. Each
operation mode is explained in more detailed below. In an exemplary
embodiment, the operation algorithm is downloaded from the remote device
34 to the programmable memory 30 through the communication unit 32. The
remote device 34 is preferably a portable electrical device such as a
smart phone, but also can be a personal computer, or simply a storage
device without any processing capabilities.

[0025] In an exemplary embodiment as shown in FIG. 3, the process of
downloading operation algorithms is initiated at the device 20. First,
the device 20 is selected to be in a connection mode (step 300), and then
the option of "update profile" is selected (step 302). The device 20 will
attempt to connect to the remote device 34 in this mode (step 304). After
establishing connection, the display unit 22 will start downloading all
operation algorithms stored in the remote device 34 (step 306). The
result of the transfer, either success or fail, will then be displayed
(step 307 or 308), and the process ends at step 310. In another
embodiment, the available operation algorithms are displayed on the
device 20 for the user to choose to download before the download starts.

[0026] In an exemplary embodiment, the downloaded operation algorithms can
be deleted from the programmable memory 30. This feature ensures that the
limited size of the programmable memory 30 will not be permanently wasted
for modes that are no longer useful to the user. New operation algorithms
can also be downloaded to replace the deleted operation algorithms. In an
exemplary embodiment, the condition for starting the deletion process is
sufficiently complex in order to prevent accidental deletion. In a
specific embodiment, a first combination of control buttons 26 are
simultaneously pressed for a first predetermined period of time, then a
second combination of control buttons 26 are then subsequently
simultaneously pressed for a second predetermined period of time to
trigger a deletion process. It is obvious that the number of such
combinations are arbitrary and is preferably to be three or above.

[0027] In one embodiment, there are three control buttons on one side of
the apparatus 20 for the users to select and control the apparatus 20.
They are labeled as K1 (26a), K2 (26b) and K3 (26c) in FIGS. 4 to 7
respectively. These control buttons serves as navigation keys for the
users to select the particular operation algorithm to invoke, to navigate
along the sub-menus provided by that operation algorithm, and also as
input keys for the users to enter a value or a parameter required by the
operation algorithm.

[0028] In an exemplary embodiment, a first operation mode is a time mode.
As shown in FIG. 4, the time mode can display at least one time data on
the display unit 22, such as a first time 37a and a second time 37b. The
time mode functions like a general clock, and alarm functions can be set
by the user. In one embodiment, this mode is permanently installed in the
device 20 separate from the programmable memory 30.

[0029] In an exemplary embodiment, a second operation mode is a calorie
coach mode. FIG. 5 shows the state flow diagram of the apparatus in this
mode. In general, the apparatus displays a message on the display unit 22
and wait for user input. The message may contain a text or a text plus a
parameter value. The user can then make use of the control buttons K1
(26a), K2 (26b) and K3 (26c) to input a value or to navigate to another
state. As shown in FIG. 5, the calorie coach mode allows the user to
enter the intended calorie balance and the amount of calorie intake. The
calorie balance equals to the subtraction between the calorie intake and
the calorie consumption. After the input, the display unit 22 then shows
the amount of allowable calorie intake in order to achieve the intended
calorie balance. In the absence of calorie input, the system will prompt
the user to enter a value by popping up a message of "pls input calorie"
for a predetermined duration, say 3 second. If a value is not entered
within the predetermined time, the system will use the default value for
calculation. The calorie coach mode can also calculate the calorie
consumption based on the types of exercise of the user such as running,
swimming and cycling, etc.

[0030] In an exemplary embodiment, a third operation mode is a running
mode. The operational state diagram is shown in FIG. 6. In the running
mode, the apparatus receives heartbeat rate information from a chest belt
separate from the watch and displays on the display unit 22. In one
embodiment, the running mode also shows a time period of the run, the
running speed through an internal or external accelerometer or termed
Speed and Distance (S&D) sensor, an amount of calorie burned and/or lap
information. Similar to the other modes, the user can use of the control
buttons K1 (26a), K2 (26b) and K3 (26c) to navigate and each of these
parameters can be displayed together or in predetermined combinations,
depending on the size of the display unit 22.

[0031] In an exemplary embodiment, a fourth operation mode is a workout
mode. The operational state diagram of this mode is shown in FIG. 7. The
workout mode has counters to count repetitions and number of sets. The
period of rest time between sets, or other times such as time elapsed
within a repetition can also be counted and displayed. Similarly, an
amount of calorie burned can also be detected and displayed.

[0032] In an embodiment, a fifth operation mode is a hiking mode. The
hiking mode displays a direction of the watch from an internal or
external compass, for example in the form of cardinal points. The
latitude and longitude of the watch are also displayed for example from a
link to a device with global positioning system. A barometric pressure
sensor can also be installed in the device and the pressure can be
displayed.

[0033] In an embodiment, a sixth operation mode is a fishing mode. The
fishing mode displays a fish amount prediction based on predetermined
parameters, and also moon phase data which affects fish behavior. The
moon phase data information is not affected by weather, and thus is more
reliable than the naked eye.

[0034] In an embodiment, a seventh operation mode is a weather forecast
mode. The weather forecast mode displays a current weather such as sunny,
cloudy or raining etc., and can also display a forecast for a
predetermined period of time. Internal or external thermometers and/or
humidity sensors can also allow temperature and humidity information to
be displayed on the display unit 22. Any weather alerts, such as typhoon
warnings, snow alert, or any other alerts issued by the government can
also be displayed by connecting the device 20 to the appropriate sources,
or to the remote device 34.

[0035] In an exemplary embodiment, data or parameters displayed on the
display unit 22 in any of the operation modes can be recorded and
uploaded back to the remote device 34. In one embodiment, the recorded
data type is fixed for each operation mode, while in other embodiments
the recorded data type can be customized. The data is stored in the
programmable memory 30 for a predetermined period of time in order to
limit memory usage, and will be permanently deleted if the data is not
uploaded to the remote device 34 within the period of time. Once the
upload is completed, the uploaded data will also be deleted from the
device 20.

[0036] In an exemplary embodiment, the display unit 22 of the device 20 is
made of a black-and-white LCD display with backlight. This option ensures
minimum power consumption for displaying the necessary parameters such
that the majority of the power can be used for communicating with other
devices and/or detecting the parameters.

[0037] The exemplary embodiments of the present invention are thus fully
described. Although the description referred to particular embodiments,
it will be clear to one skilled in the art that the present invention may
be practiced with variation of these specific details. Hence this
invention should not be construed as limited to the embodiments set forth
herein.

[0038] For example, the operation modes listed above are only described by
way of example but not limitation. It is obvious to one skilled in the
art that any combination of parameters displayed and detected, either
through internal or external sensors, are possible without departing from
the spirit of the invention. In one embodiment, the user can customize
the combination of parameters displayed through a program for example in
the remote device 34.
